Fleetguard AF55318 Air Filter
The Fleetguard AF55318 is a high-performance radial seal primary air filter of the Magnum RS Series, engineered by Cummins Filtration for heavy-duty agricultural and construction machinery, perfectly matching John Deere, Cummins and other mainstream platforms. As an OEM-grade replacement part, it features precision structural design and strict dimensional control, ensuring seamless fit with original equipment and reliable airtightness of the intake system, eliminating air leakage risks in complex working conditions.
Adopting advanced multi-layer composite filtration media with scientific pore size grading, the filter excels in fine particle capture. It can effectively trap dust, sand and airborne contaminants in farmland and construction site environments, preventing abrasive particles from entering the engine and protecting key components such as cylinders and pistons from premature wear, thus safeguarding engine normal operation.
Built with rugged and durable materials, the AF55318 is designed for harsh working scenarios. Its high-strength end caps and tear-resistant filtration media enhance overall structural stability, and the optimized air flow design reduces intake resistance while maintaining superior filtration performance, supporting continuous and stable power output of heavy-duty equipment during long-term high-load operation.
Advantages of AF55318 Air Filter
The AF55318 features superior filtration performance, relying on premium composite media and precise pore size design to capture over 99.99% of fine particulates in the air. It forms a solid protective barrier for the engine intake system, effectively reducing internal component wear and extending the service life of the engine and its associated parts in dusty working environments.
It boasts OEM-level perfect compatibility and easy installation. The filter is strictly designed to match the dimensional and structural requirements of original agricultural and construction machinery, with a reliable radial seal structure ensuring quick and accurate replacement without additional modification, greatly saving maintenance time and improving equipment operational efficiency.
The filter is engineered for extreme durability and environmental adaptability. Its rugged metal end caps, high-temperature and wear-resistant sealing materials make it resistant to vibration, dust erosion and temperature changes, maintaining stable filtration performance under the harsh and complex working conditions of farmland and construction sites, avoiding premature filter failure.
It delivers excellent long-term cost-effectiveness for users. With an extended service interval and long service life, the AF55318 reduces the frequency of filter replacement and daily maintenance costs. By effectively protecting the engine and reducing the risk of unexpected failures, it further cuts down the overall operational and maintenance expenses of heavy-duty equipment, maximizing user economic benefits.
